To all whom it may concern:

Be it known that I, J ACOB Oonsnnn, a citizen of the Republic of Switzerland, residing at Miillerstrasse 56, Zurich, Switzerland? have invented certain new and useful Improvements in Apparatus for Discharging Dust-Carts into the Furnaces of Refuse-Destructors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

In order to discharge refuse or dust from dust boxes or bins into dust carts without making a dust, the dust boxes or bins are provided with sliding lids or covers, which act in conjunction with a sliding lid or cover on the dust cart or cart body in such a way that the escape of the dust raised is prevented. In order to discharge the boxes or bins of the dust carts into the refuse destructor furnace, the bins are then raised over the shaft of the furnace and discharged into the shaft by opening the bottom.

Now this invention has for its object an arrangement which enables the boxes or bins of dust carts to be discharged into the furnace without allowing any dust to escape, a frame adapted to travel over a series of furnace shafts being automatically coupled with the cover of a furnace shaft and, when a bin or box is on the frame the cover is raised, after which when the frame is moved along the cover is moved off the furnace shaft, the bottom of the bin or box opened, and the bin moved into position over the furnace shaft.

One form of construction of the invention will now be more particularly described with reference to the accompanying drawings, in which:

' Figures 1-3 are side views of the arrangement with the movable parts in various positions; Figs. 4 and 5 are sections of the arrangement with the movable parts in various positions; Figs. 6 and 7, a section and plan view respectively of the arrange ment on a reduced scale; Fig. 8 is a cross section of the box or bin; and Figs. 9 and 10, details on an enlarged scale of the hook positioning means.

1 are the upper parts of refuse destructor i furnaces, which have a suitable number of i' furnace shafts 2, 3, in proximity to one an other. Covers or lids 4 lie loosely on the said shafts and are covered on their under side with a fire proof layer 5. Each furnace cover 4 has two lateral yokes 6 which are connected by a horizontal bar 7 (Fig. 7).

A framework 10 travels by means of wheels 9 on rails 8 and has a frame 11 in which the under part of a dust box or bin 12 of a dust cart may be inserted, the bars 13 of the box or bin (Fig. 8) resting on the frame 11. The upper parts 14 of two sides of the dust box or bin, (of which boxes several are removably mounted on a dust cart one behind the other) are widened out laterally and merge gradually into the lower part 15 with curves which approach one another. The box is closed below by a sliding door 16 which is secured by a bolt 17. The bolt has a projection 18 at the top. A yoke, one arm 20 of which has its ends formed as hooks, while the other arms 21 are connected by a crossbar 22, is fixed on the frame 10 on a bar 23 pivotal in hangers 19. A projection 24 is fastened on one end of the bar 23 (Fig. 10), which projection has a short pin 25 extending in the same direction as the bar 23. A hook 26, which is longer than the projection 24, is loosely mounted on the bar 23. The pin 25 in its normal position rests loosely against the hooks 26 (Fig. 9 full lines). A stop 27 which has on top a straight surface 28, is provided on the side of the rail 29 is a second stop. The stops 27 and 29 are arranged at certain places by each furnace shaft (Fig. 7). A bar 30 is provided on one side of each box or bin 12.

81 are angular guides on the frame 11, which facilitate the insertion of the bins or boxes. Draw ropes 82 are secured to the frame 10 in front and at the rear respectively, which ropes may be wound up on rollers 33 and 34, which are connected by a chain 37 running over chain wheels 35, 36.

When a box or bin of a dust cart filled with dust is to be discharged into the refuse destructor furnace, the frame 10 is first brought into the position with respect to the furnace shaft 3 in which it is shown in Fig. 1. If the frame be then moved forward a little in the direction indicated by the ar- 8 in the path of movement of the hook 26.

row into the position shown in Fig. 2, the

hook 26 encounters the stop 27, and thereby turns the pin 25 and the projection 24, the bar 23 and the yokes, so that the hooked arms 20 drop down. The hook 26 rubs on the guide surface 28. When it slips off the latter, the hooks of the arm 20 engage under the crossbar 7 and hold it (Fig. 3). The box or bin is then raised, for instance by a crane, over the furnace and lowered in such a way that it rests in the frame 11 (Fig. 4). The bar 30 then presses down the crossbar 22 of the yoke, the cover l is raised, and at the same time the nose 18 of the bolt 17 is held away from the frame 11, so that the sliding door 16 is now loose. Two bars 38, 39, mounted on its under side have, however, engaged two projections A0, 41, on the furnace, which prevent the slide being displaced. Now if the frame 1 be moved farther in the direction indicated by the arrow,

until the hook 26 encounters the stop 29, the cover 1 is simultaneously removed from the furnace shaft 3 (Fig. 5), the box or bin moved over the furnace shaft 3, and by the retention of the sliding door 16, the bottom of the box opened so that the refuse can drop into the furnace without any dust escaping, l/Vhen the discharge of the box or bin 12 is completed in this way, it is drawn back, the operations taking place in a reverse succession. When the furnace shaft 3 is filled, the hook 26 is thrown over into the position in which it is shown by dotted lines in Fig. 9. The yoke has now the position shown in Fig. 6 and thus the frame 10 can be run over the bar 7 on the furnace shaft 3, without its being coupled with the furnace cover 4. If then the hook 26 be again moved, the cover 41 of the shaft 2'can now be coupled with the frame, so that this furnace shaftf can be fed without any dust escaping.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is:

1. Apparatus for discharging dust into covered receptacles, comprising a movable frame, a lifting member thereon, means 0perated by the movement of the frame to move the lifting member into position to engage the cover of the receptacle, and a dust box adapted to be placed in the frame and to actuate the lifting member to raise the cover.

2. Apparatus for discharging dust into covered receptacles, comprising a movable frame, a lifting member on the frame, means operated by the movement of the frame to move the lifting member into position to engage the cover of the receptacle, a dust box having a sliding bottom adaptedto be placed in the frame, said lifting member actuated by the box when placed in the frame to raise the cover from the receptacle, and means to automatically withdraw the bottom from the box during the movementof the frame. 7

3. Apparatus for discharging dust into covered receptacles, comprising a frame adapted to travel over the receptacle, a dust box adapted to be placed in the frame, a coupling between the frame and cover of the'receptacle, a sliding bottom on the box and means for connecting the sliding bottom to the top of the receptacle.
